I’m currently doing a YouTube tutorial called “PLC programming using TwinCAT 3“, which is one of the biggest hobby projects I’ve ever committed myself to. When I started with the tutorial I had a gut-feeling that it would probably take a huge amount of time to pull this one off. Initially, I guessed I would have to spend around five minutes of work for every minute of produced movie (ratio of 5:1). Now that I’ve done a couple of videos and actually clocked the time it takes all I can say is that ….boy, was I completely off with that guess! Lately I have been receiving many e-mails and messages with the question “When is the next part of the tutorial coming out?”. Instead of just providing the boring and generic answer “When it’s finished” I have decided that I will instead try to explain what it takes to do a YouTube video, and why I am not releasing a video every week.
I have reached 1000 subscribers on YouTube! I never thought I’d get anywhere close to this huge amount of subscribers, especially not this fast! Since I published the first episodes of the “PLC programming using TwinCAT 3 tutorial” in the beginning of March on YouTube, the channel has received over 30.000 views. It seems free PLC programming tutorials are appreciated. It’s time to celebrate and answer some questions that I’ve got from you viewers!
Sharing knowledge with other TwinCAT developers using a blog is not only an easy and good way, but it’s also quite fun. After a long day at work, I often find it enjoying to sit down and write a little bit on a new blog post. Quite recently I launched TcUnit – the TwinCAT unit testing framework and even though there now is tons of documentation and example code on the official website, some people prefer to learn by watching a video. For this reason I’ve created a series of four videos that will introduce TwinCAT software developers to test driven development (TDD) and how to do TDD using TcUnit.
